abies born with CF don’t gain weight as expected. They fail to thrive in spite of a normal diet and a good appetite. Mucus blocks the passageways of the pancreas and prevents pancreatic digestive juices from entering the intestines. Without these digestive juices‚ the intestines can’t absorb fats and proteins completely‚ so nutrients pass out of the body unused rather than helping the body grow. Poor fat absorption makes the stools appear oily and bulky and increases the child’s risk for deficiencies

was tested against the bacteria E. coli and S. aureus. The resulting Numerical value was 2.5 for E. coli and 3.0 for S. aureus. The bureau used the standard parameter 1-2- slightly inhibited and 3-5 as partially inhibited. Thus‚ the inhibition of the mango leaves extract and coconut oil in E. coli was slight and it is partial in S. aureus. The researcher concluded that mango leaves extract with coconut oil can kill bacteria like E. coli and S. aureus. It can also be concluded that it can help wounds

I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

CATALASE Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in reproductive reactions. Likewise‚ catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second. Catalase is a tetramer of four polypeptide chains‚ each over 500 amino acids long. It contains
